Abstract: This paper presents the results of nondestructive aluminum test samples testing using active pulse infrared thermography technique. Test samples, contain inside grooves of different widths at different depths, as testing defects. Subsurface defects detection and analysis were performed by comparing experimental results to results of simulation.
